Here is a list of Broadway shows, alphabetically, that have “love” in the title, more than 200 in all. The earliest is “Love for Love” by William Congreve in 1750, a play that popularized the line “you must not kiss and tell,” and that has been revived on Broadway six times, most recently in 1974. The latest, “Living on Love,” doesn’t open until April, 2015, and a revival of Sam Shepard’s “Fool for Love” is scheduled for October. Best titles: “Love in a Coffee Cup,” “Love and Libel,” “Love Laughs,” “Love Kills.” The longest-running show on Broadway with “love” in the title was: “I Love My Wife,” the Cy Coleman musical from the 1970s, which ran for 857 performances. Five were performed only once. “Love” doesn’t always last, but it never ends.
